She suggests that you ask yourself if today mattered in the grand scheme of things, every day:

…when you ask yourself this question, chances are you’ll know the answer intuitively. Did today matter? If so, great. Do more things like it tomorrow. Can’t remember anything in particular that made a difference? Well, better change it up.

It’s deceptively simple, yet one of the most important things you can ask.

It feels good to be the best. You get recognition, a sense of accomplishment, and hopefully compensation. If you’re the best person in the room, though, you’re probably not getting challenged anymore.

Being the worst person in the room gives you motivation to get better so you’re not on the bottom anymore. However, being the top of your class probably means it’s time to move on to another class. No matter where you are, as long as you’re not afraid to challenge yourself, you can continue to improve and make yourself more valuable to the room.
